产品概述：
吸吮式自清洗过滤器又名以色列过滤器,自清洗过滤器。有两种结构型式:立式、卧式。吸吮式自清洗过滤器具有对原水进行过滤井自动对滤芯进行清洗排污的功能,且清洗排污时系统不间断供水。

     产品广泛应用于冷却水水处理:冷却塔、补充水系统、空调系统、直流系统水过滤,减少热交换器内沉淀物的产品,保持其冷却效果。原水处理:可对地表河水、湖水、海水、水库水、井水及地下水进行过滤,除去沙子、细菌、藻类、有机物等等。工业循环用水过滤:在对水质有一定要求的设备。如:冷却塔、轧机、连铸机、抛光、水泵、电磁阀、离子交换器、喷雾器、热交换器或供排水管路上使用,可过滤掉水中杂质,避免管路、喷嘴等零部件堵塞。灌:尤其适用于高流量、杂质含量高的水源,农业灌溉、喷滋公园、高尔夫球场、草皮浇灌等。造纸工业:白水过滤。塑料工业:产品回收冷却水过滤。

Product overview:
Sucking type self-cleaning filters, also known as Israeli filters, self-cleaning filters. There are two types of structure: vertical and horizontal. The sucking self-cleaning filter has the function of automatically cleaning and draining the filter element by filtering the raw water, and the system continuously supplies water during cleaning and draining. Products are widely used in cooling water treatment: cooling towers, make-up water systems, air conditioning systems, DC system water filtration, products that reduce sediments in heat exchangers and maintain their cooling effect. Raw water treatment: it can filter surface river water, lake water, seawater, reservoir water, well water and groundwater to remove sand, bacteria, algae, organic matter and so on. Industrial circulating water filtration: Equipment with certain requirements on water quality. Such as: cooling towers, rolling mills, continuous casting machines, polishing, water pumps, solenoid valves, ion exchangers, sprayers, heat exchangers or water supply and drainage pipes can be used to filter out impurities in the water to avoid blockage of pipes, nozzles and other components. Irrigation: Particularly suitable for high-flow, high-impurity water sources, agricultural irrigation, spray parks, golf courses, turf irrigation, etc. Paper industry: white water filtration. Plastic industry: product recycling cooling water filtration.

工作原理：
吸吮式自清洗过滤器通过监测进出水口压差,确定洗时机,当压差达到设定值时0.05MPa(可调),开始自动清洗程序,通过吸嘴在滤网内部扫描式淸洗,打开排污阀排污,清洗完成后,关闭排污阀,马达停止,系统恢复至其初始状态,为下一个过滤程序作好准备。此间净水供应不中断。也可通过时间设定来控制清洗排污。

working principle:
The suction type self-cleaning filter determines the washing time by monitoring the pressure difference between the inlet and outlet. When the pressure difference reaches the set value of 0.05Mpa (adjustable), the automatic cleaning procedure is started. The filter screen is scanned and cleaned through the suction nozzle, and the blowdown valve is opened for blowdown. After the cleaning, the blowdown valve is closed, the motor stops, and the system returns to its initial state, so as to prepare for the next filtering procedure. There is no interruption in the supply of clean water. The cleaning and blowdown can also be controlled by time setting.
